IMPROVEMENT IN PAPER-FILES.

'TO ALL WI-IOM IT MAY OONCERITi Be it known that we, ELDRIDGE J. SMITH and BENJAMIN H. Onnnvnn, of Washington city, in the county of Washington, and District of Columbia, have invented a new and useful Improvement in Paper-Files; and we do hereby declare that the following is a full, clear, and exact description of the construction andpperation of the same, reference being bad to the accompanying drawings, making a part of this specification, in which- Figure 1 is an elevation of our improved paper-file.

Figure 2 is a perspective view of the same.

Figure 3, a-detached view of adjustable plate A; and

Figures 4 and 5, similar view, and'showing a modification of this invention.

Like letters in both figures of the drawings indicate like parts.

' The nature of our invention consists in an adjustable plate, provided with braces having transverse lugs or cars working in slots or rabbets formed-in the under edge of the bottom-plate, to which bottom-plate is attached at right angles thereto, forming the end of the file. The adjustable plate slides over the bottom-plate, and holds the papers against the end-plate, and is held in position by means of the transverse lugs or cars, which catch against the under side of the bottom-plate, as shown.

To enable others skilled in the art to make and use our invention, we will proceed to describe its construc: tion and operation.

We construct three plates, A, B, and C, of wood or other suitable material, and of suitable size, say, six inches long, three and a half inches wide, and one-fourth of an inch thick, to plate A. We attach braces" with arms'D D, and transverse lugs or cars E E, at the bottom of the projecting ends'of the arms, which lugs extend below the ends of the plate A, and also laterally toward the plate C, as shown, the lugs-being attached,- not opposite the end of plate A, but at the bottom of the projecting ends ofv the arms, so 'as to form a proper brace for and to hold in position the adjustable plate A, (see figs. 2 and 3.) Grooves or rabbets, HH, are formed .in the under edges of the plate B, to secure the lugs E E, as clearly shown in the drawing. Weattaoh plate C at one end of and at right angles to plate B, by means of dove-tails, and strengthen them by the braces F F, which are let in'flush with the edges of the plate.

Operation. By pushing on the adjustable plate, it is readily moved and made to clamp the papers G against the plate C, and is held in position by means of the transverse lugs or cars E, which catch against the bottom of plate B,

and by pressing the topof the adjustable plate toward plate C, the clamp is loosened and allowed to slide back.

In the modification shown in figs. 4 and 5, the lugs E E are shown as connected together, forming a continuous bar across the bottom of plate A, which may, for some uses, be a preferable form of device, the principle, however, remaining substantially-the same in either case. I

Claim.

Having thus fully described our invention, what we claim therein. as new, and desire to secure by Letters Patent, is- D 1. The combination, in a paper-file, of an adjustable plate, with a base and fixed vertical plate, substantially as and for the purpose set forth.

2. The adjustable plate A, with the projecting arms D D, in combination with the bottom-plate B and'endplate C, substantially and in the manner and for the purpose herein set forth.
